T 0 all whom it may concern:

Be it known that I, HOMER 'I. YARYAN, a citizen of the United States,residing at To ledo, Ohio, have invented new and useful Improvements inProcesses of and Apparatus for Purifying Oxidizable Liquids, of whichthe following is a specification.

My invention relates to the manufacture of linseed and other oils by thesolvent process, in which the oil is extracted by digesting theoil-bearing substance with a liquid solvent, usually a hydrocarbon.Irrthis manufacture it has been usual to treat the oil by aeration atthe close, in order to drive off the final traces of the residualsolvent; andmy invention relates more particularly to this feature ofthe manufacture, its object being to improve the processes usuallyemployed with respect to the injurious oxidizing effect of the air used5 and it consists in the method hereinafter described for deoxidizingthe air to a greater or less degree and aerating the oil with suchdeoxidized air, and also in the apparatus for working such process on acommercial scale in an economical manner.

In the accompanying drawing I have shown an apparatus for carrying outmy invention, consisting, substantially, of a furnace, A, air pump orblower B, aerating-tank O, and their connecting-pipes, this apparatusbeing employed to obtain a deoxidation of the air by combustion of cokeor charcoal, producing nitrogen and carbonic acid, in which form theoxygen has a stronger affinity for its associated elements than for themolecules of the oil to be treated.

The furnace may be of any convenient construction, preferably a simplefire-pot inclosing a grate and terminating above in a chimney, a,provided with a cut-off valve, 1), (indicated by dotted lines.) Betweenthe valve 1) and the fire-pot a pipe, 0, leads from the uptake a to theblower B, either direct, as in dicated by the dotted lines, or throughan ordinary wash-box, D, in which the gases are cooled and washed bypassage through water intermediate between the furnace A and blowor B.

The blower B may be an ordinary rotary pressure-blower, or any form ofair-pump by which the current of air may be drawn through theincandescent fuel and pipe c,.and forced forward through the pipe (Zintoa coil, (1, arranged in the bottom of the aerating-tank C, whence itis discharged upward through suitable perforations into the containedliquid in the usual manner.

Various modifications of the above-stated method of applying theessential principle of my invention may be employed, such as deoxidizingthe air by the-use of chemical absorbcnts; but for practical purposesthe method described is found to be most efficient and economical, andis therefore preferred.

The operation is sufficiently obvious. The valve 12 is left open instarting the tire, after which it is closed, and the products ofcombustion carried by the action of the blower through the pipes c d anddischarged through the coil (1. Where the heat of the gases is notobjectionable, the wash-box D may be dispensed with. I I

I claim as my invention and desire to secure by Letters Patent I 1. Theart or process of purifying liquidssuch as oils containing residualtraces of a hydrocarbon or other vaporizable solvent-consisting in firstdeoxidiziug air, then treating the liquid with such product by theordinary method of aeration, substantially as set forth.

2. The art or process of purifying oxidizable liquidssuch as oilscontaining residual traces of a hydrocarbon or other vaporizablesolventby drawing air through incandescent coke, charcoal, &c., andforcing the gaseous product of combustion through the liquid, as in theordinary process of aeration, substantially as set forth.

3. The art or process of purifying oxidizable liquidssuch as oilscontaining residual traces of a hydrocarbon or other vaporizablesolventby drawing off the gaseous product of the combustion of coke,charcoal, &c., cleansing and cooling the same by passage through wa ter,thence forcing the same in a finely-divided state through the liquidunder treatment, substantially as set forth.
